* Add basic support for .debug_ranges section to LLVM's DebugInfo library.Alexey Samsonov2012-08-271-1/+5
| | | | | | | | | | | This section (introduced in DWARF-3) is used to define instruction address ranges for functions that are not contiguous and can't be described by low_pc/high_pc attributes (this is the usual case for inlined subroutines). The patch is the first step to support fetching complete inlining info from DWARF. Reviewed by Benjamin Kramer. llvm-svn: 162657

* Sketch out a DWARF parser.Benjamin Kramer2011-09-131-0/+93
This introduces a new library to LLVM: libDebugInfo. It will provide debug information parsing to LLVM. Much of the design and some of the code is taken from the LLDB project. It also contains an llvm-dwarfdump tool that can dump the abbrevs and DIEs from an object file. It can be used to write tests for DWARF input and output easily. llvm-svn: 139627
